Load Switch Function

NCP373 is an over−voltage and over−current protection device.

From IN to VBUS , the part acts as a load switch protection, with

programmable current regulation. The current protection is externally

adjustable, up to 400 mA or 1300 mA, depending on selected version.

Additional voltage protection is available, from VBUS to IN. Due to

built−in low R

NMOS FET, the host system is protected against

ALYWG

The embedded over−current and over−voltage protection allow the

device to sustain extreme conditions from short circuit on USB

connector, or defective WA or USB port.

12 PIN LLGA

MU SUFFIX

CASE 513AK

Because to the NCP373 using internal NMOS, the system cost and

the PCB area of the application board are minimized.

NCP373 provides a negative going flag (FLAG) output, which

alerts the system that a fault has occurred.
